fuel pump problem

i continued searching a little more for any other pumps that are available now.....i found a couple more of the bare pumps on ebay.
i went ahead and bought the one for $50...with free shipping. from china....seems like all of them are from china. probably one manufacturer for all of these being sold...including yamaha replacement part ??? who knows? the important thing is it needs to not lock up after it's hot and to also provide enough fuel and pressure to keep the performance at normal.
hopefully i haven't bought another pump like the two i have now.

Hi, I have had this problem last weekend, heat one day I stopped to get gas and never worked, the pump was dead, but after 30 minutes I start the bike.
You recommend buying these from China that sell on ebay?
My WR is 2009 with 4200 KM

I thought it would be worth a chance to try..... it being $50 vs $250+ for a Yamaha complete pump and housing assembly. I had already bought a Yamaha replacement pump before and now it was failing. this $50 bare pump from ebay.... for me was the better deal.
it looks exactly the same as my original and the Yamaha replacement that I had bought. exactly the same.
I have been busy with some other projects and have not had a chance to ride this bike since I swapped out the pumps, but plan to ride it soon. it makes the same prime-up sound as the others and the bike fires right up. I know (from experience) now that once the pump locks up from heat...you may only have a little more time before it gets more frequent and it takes longer and longer to cool or whatever before it will operate again.
if you or anyone else reads this and decides to replace the bare pump in your housing, just be patient and carefully pry each of the 3 snaps on the housing apart and then you can twist and rotate the two parts around to remove the old pump. no need to remove the (black) plastic line between the two housing pieces. I doubt you could without destroying it anyways.

Hi, dirtytrixx, Thanks! I'll try the ebay pump, could you send me the eBay link were you bought yours? Thanks again for your time

mine came with a new filter and a new push on retainer clip...but neither were right for our application so I just installed my filter and reused the retainer clip. the new clip that came with the pump was not a good tight fit like the original clip. again...be patient with removing your original clip...it will come off.

good luck on your repair. it really is not very much to it though. should not have any trouble.

added note:
got in a decent fun ride this afternoon and the new pump works as it should. no notice of performance falling off when hot either.
$50 , runs great.....yea ,i'm happy  

I had posted a separate thread about a problem I was having wih my 2011 WRR. I wasn't sure that it was the fuel pump at first, because mine was showing different symptoms than what I had read about in other threads. But in the end it did turn out to be the fuel pump. So I wanted to post in this thread to add to the database. To summarize:
When the problem first appeared, the bike acted just like I had blipped the kill switch for a moment. It varied from about 1/2 second to 2 seconds. The engine would die, and then immediately come back on. This happened consistently for about a week, and only when the bike was completely warmed up, like at least 10 miles into a ride. It was more likely to happen when temps were in the 70s or higher. I did one all-day ride when it was in the 60s, and the problem never occured. After about a week, it got worse, and the bike would sometimes die completely, but would restart after just a few seconds. Once it started happening, I could only ride a hundred yards or so before it would die again. When the bike was cold in the morning, it would start and run just fine until it got warmed up.
I installed a new OEM pump, the updated version, Yamaha P/N 3D7-13907-10. So far I've ridden 150 miles or so with temps in the 80s, and the bike has run flawlessly.

Just ordered the updated 3D7-13907-10-00 Fuel Pump Complete from yamahasportsplaza.com so we'll see if the updated unit really is the solution we're all hoping it is.

In my research, I also found a replacement fuel pump motor Part Number: HFP-389 which carries a LIFETIME Warranty!!

This one comes from Axiom-Performance, HighFlowFuel.

If the new updated OEM pump assembly craps out again, I may try the lifetime motor swap or simply trade it for a dependable Honda 250!!

Hi folks,
Pump on my 2008 has given up the ghost. Do these new pumps just strap on the top of the old or do I need to take the thing apart? Te picture looks like it just plumbs in rather than taking the housing apart.

You'll have to strip the old pump housing apart to fit the pump.
Have fun !

Hi All,

I've zeroed in on getting a used WR250R dual sport, and everything I've read points to this being the perfect bike for my needs. But clearly there are fuel pump issues with this bike. At first I thought it was just the early 2008 models. But the more I read, the larger the span of time and models that seem to be having pump failures. I've spotted some 2008 models that I could purchase...but I am hesitant now that I have read so many fuel pump disaster stories. Should I just avoid the older models altogether? Is there a year where the fuel pump flaw or bad design was finally resolved? I've seen evidence of failure all the way thru '08 and into '09 and '10 so far, with mixed opinions on replacement/aftermarket pumps. I've lost count of how many WRR owners have talked about being left stranded when the pump fails temporarily or permanently. What says the community about this issue? Thanks much!

I got a 2008 WRR and I've ridden the heck out of it, including remote solo singletrack, with no problems so far! If it happened to fail at the wrong time, I may be walking a bit.

Just imagine how many WRR's have been sold vs. how many fuel pump failures have been reported, and you can gage your own risk tolerance.

Possible fuel pump fault is an "over stated non issue".......unless it happens to you of course, lol.

Anyway i'd say just go ahead with a purchace if you find a suitable bike, and if you are really worried about this possible problem then just buy a new F/P..... I think from memory that some guys on here have brought new genuine pumps from " Service Honda" ? USA for around $150 ?.

Just do it and enjoy the overall riding fun of this little 1/4 litre machine.
Always look back and regret something you HAVE done - rather than something you wish you did !

Cheers.

The fuel pump on my 2008 failed around 16k miles or so. I figured since it had lasted over 10k miles it would go forever. Nope!

Taking the fuel pump cage apart was a pain, but definitely doable if you take your time and shave down the tabs carefully with a razor blade. Now I even carry a spare fuel pump (not the whole assembly) with me on my 2013. I already shaved the tabs on it so I can do a trail side replacement. I've almost been stranded in the middle of a desert because of fueling issues so I see the value in being thorough.

So I am new to the world of WRR ownership and looking to prepare the bike for some long back adventures. Have there been any failures of the new part number 3D7-13907-10-00 fuel pump yet?

I did a quick search around the forums and I have not found the new part number called out specifically. I'm the optimistic sort and I'm hoping that it could be solved.

The pump on my 02/2008 WR250R failed last summer, in a most embarrassing fashion. The first time it acted up, I was on my way in to work and stopped to get gas 20 miles into my commute. It didna start back up, so I had to manage to get the rest of the way to work using the local light rail, then more rail to get back home. On the weekend I toodled on up to pick up the bike with my truck. Of course, the bike fired right up.

That wasn't the embarrassing event, merely the foreshadowing. A few weeks later, I took a ride on a Saturday, and decided to stop in at the local Harley shop, which has a fairly decent eatery, for lunch. My WR wouldn't start. Yes, my Yamaha DP died in the parking lot of a Harley dealership...

Circumstances and priorities meant that I didn't get around to finding out what the problem was, nor get it resolved until yesterday. Yup, fuel pump. Worg (my name for the bike) is a happy camper now.

Why, some may wonder, did it take so long to fail? Given that the failures are heat related, and I'm living in Utah's desert, it would seem odd. Except... I'm the second owner. The first owner bought the bike up in Alaska and put the majority of it's miles on it up there. He barely used the bike after he moved down to Wyoming (not exactly a toasty locale either) before selling it to me, where I wasn't able to use it much until the following late spring.

Okay so I bought this bike new in 2010 and about 1000 miles into owning the bike it wouldn't fire up for me leaving me stranded. Thankfully the bike was still under warranty and the fuel pump was replaced without costing me anything. Fast forward 16,000+ miles and my bike starts to not fire up after it has been running fine for a while. It'll start up just fine when the engine is cold but after running for a while and I stop (i.e. getting some gas or whatever) the bike will not start back up.
Did some research and it looked like I could either buy a new OEM pump for about $250-$300 or a new fuel pump (without the plastic housing that the OEM comes with) on amazon for about $30. I choose to go the Amazon route and try dissembling the plastic housing myself. I used a cotter pin removal tool and a medium size flathead to get the plastic tabs up to remove the original pump and it worked just fine. A little frustrating but that was because I didn't want to break the plastic housing and end up buying the 10x more expensive OEM pump. I got 2 of the 3 tabs up and was able to finagle it. Sorry I didn't take any pics to post but it is pretty straight forward. The nice thing about the $30 pump is that it came with 2 fuel filters too. I thought it was a good deal for $30.

The bike starts up just fine now anytime, Cold or hot!

My replacement pump failed after only 6000 miles this time. It was supposedly the updated version, P/N 3D7-13907-10-00. (See my last post in this thread, 11 posts up.)
This time I installed only the pump, filter, and hose into the stock module. I bought the kit here:

We'll see how long this one lasts.....

Need a spare to put on stock.

Ordered http://www.ebay.com/itm/New-Yamaha-Intank-EFI-30mm-Fuel-Pump-for-WR25R-WR25X-2008-2012-/181236341992?hash=item2a32871ce8:g:2jMAAOSwxH1T7YrR&vxp=mtr#shpCntId

Seems to included the lot whats needed.

I posted back in 2010 when my stock '08 pump went out somewhere around 4K miles. Got a new Yamaha one then. Just left me stranded yesterday (fairly hot out) with around 9K miles. Just bought a Kemso motor off eBay. The only reason I chose that one is because it says it's made in Japan and designed with ethanol in mind. Hopefully will be good long term!

Reading topics about the fuel pump.
Nobody mentioning using a std. steel tank or a big plastic tank.
There is a lot of heat insulation at the std tank. From the outside free air flow isnt great.
Can imagine plastic tanks releasing heat different.
No idea whats the more bad the steel or the plastic.
Do the plastics come with insulation.
Do the black plastic give more trouble than the white.

60dgr / 140F shouldnt trouble any kind of device, thats isnt the critcal operating temp,om any kind of part.

So why it fails?

Ethanol or just dirt.

Or is it the typical WR size of 30mm diameter, most others are >35mm.

Car pumps last forever if you ask me.
Lots op street bike pumps easily do 60k mls or never brake.

Why not a general recal or clear courtesy policy.

I think its idiot. Doesnt belong to outback riding, carrying this type of spare parts.

TioJose: How did the HFP pump replacement go?  Any issues or installation problems?

Thanks!

Its for spare. Mine isnt broke. Only want a complete set with all parts.
Status quo.
Recieved 1 pump + 1 screen.
Complained about missing parts and made clear i wanted parts that fit.
Made clear "comply" to the advert.

Reaction this morning.
We are sending the hose from the advert with another option as well. It is tough with motorcycle fitments as we think we have our fitment data 100% correct but then there is always someone that has a different set-up. We pioneered motorcycle fuel pump replacements 10 years ago and have researched all of our fitment data ourselves. We strive to make sure we always send out the exact components needed for each year, make, and model so we do apologize you didn't receive what you needed.


By the way, the flex hose isnt needed. Possibly they change the advert pic thats up to them.
I pointed for a fitting black hose and clamps.

Thanks for update, TioJose.

The amount of aftermarket fuel pumps is a jungle to navigate.

KEMSO 13001 looks like an interesting more trustworthy alternative. Made in Japan, some sort of quality testing, lifetime warranty etc. Looks a bit more confidence inspiring than the cheapest chinese pumps (or same pumps sold at a high price by other retailers).

Simply, what aftermarket pump to buy these days?

Bought the Kemso as a spare. Looks solid, but haven't tested it. Fuel connection pipe isn't ribbed as Cycleworks is.
